Job Description

We have an opening for a Postdoctoral Researcher to conduct research in the development of next generation ultra-low density materials using a combination of additive manufacturing and advanced templating techniques. You will actively participate in the design, synthesis and development of functional photoresists and will be expected to characterize the reaction kinetics of various photo-polymerization processes, providing both experimental data and validation in support of an on-going effort to develop predictive computational physics models. This position is in the Materials for Energy and Climate Security group within the Materials Science Division.

You will 

  • Formulate, synthesize and characterize advanced or unique photoresists for high resolution two-photon lithography (TPP), as well as stereolithography (SLA) based 3D printing.
  • Develop methods and/or utilize existing tools to monitor and characterize reaction kinetics related to photopolymerization processes used in additive manufacturing.
  • Develop and optimize procedures to degrade or remove 3D-printed polymeric scaffolds.
  • Test, monitor and interpret mechanical and thermal properties of 3D printed materials.
  • Collaborate with scientists in a multidisciplinary team environment to accomplish research goals.
  • Document research; publish papers in peer-reviewed journals, and present results within the DOE community and at conferences.
  • Pursue independent but complementary research interests and interact with a broad spectrum of scientists internally and externally to the Laboratory.
  • Perform other duties as assigned.


  • Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. Citizenship.
  • PhD in Chemistry, Chemical Engineering, Materials Science, or a related field.
  • Experience in one or more of the following areas: organic or inorganic chemistry, polymer science, synthesis, additive manufacturing, photochemistry.
  • Experience in monitoring chemical reaction kinetics.
  • Experience in measuring mechanical and thermal properties of polymeric materials.
  • Ability as an innovative experimentalist with a broad range of experience in experimental design techniques and execution.
  • Ability to develop independent research projects through publication of peer-reviewed literature.
  • Proficient verbal and written communication skills as reflected in effective presentations at seminars, meetings and/or teaching lectures.
  • Initiative and interpersonal skills with desire and ability to work in a collaborative, multidisciplinary team environment.

Qualifications We Desire

  • Experience or familiarity with stereolithography and the chemistries enabling these technologies.
  • Experience with formulating epoxy resins/adhesives, silicones or other elastomers, hydrogels, biopolymers and/or other related network materials.
  • Experience with materials characterization using Nuclear Magnetic Resonance, Transmission Electron Microscopy, Scanning Electron Microscopy, X-Ray Diffraction, Fourier-Transform Infrared, Raman, X-ray Photoelectron Spectroscopy.

Additional Information

All your information will be kept confidential according to EEO guidelines.

Position Information

This is a Postdoctoral appointment with the possibility of extension to a maximum of three years, open to those who have been awarded a PhD at time of hire date.
